I'm a former 03 Cobra owner. I had a Sonic Blue coupe that was stolen and never recovered. I'm stating to plan for a new car and need some help. I was thinking of getting a 05-08 GT Vert. and maybe adding a turbo. My 03 made over 500rwhp and that's the problem. Thanks to Richo for the install. Al's ported blower kick but. I think on one pull it make 528/545 with a good AF. I hope who ever has it is enjoying it. Anyway. I need to know about what it will cost to build a 05-08 GT up to handle a 500rwhp plus? Will I save money if I use the stock block or is it cheaper to buy a complete new set-up? In addition, I was looking at a few turbo kits and any input would be great. I was thinking Hellion, Power House or Turbo horse power. All the kits look great. I do not want a HP kit. I here you have to wait a long time to get one. The way I see it, I have two options. Buy a 03-04 Cobra and start over or build a bad ass 05-08 GT. A GT500 is out due to the cost of convertable. A GT500 coupe might work once you can get one for msrp or less. Thanks guys

I'm on the Dyno right so this is going to be a quick answer, Both cars with make 500+whp, the stock bottom-end in the 05 will be a ticking time bomb,so it will need a good motor and the cobra's will not.

I say get a low milage 03 or 04 cobra. I am partial to the 03's..or go for the gold and get a GT500
